Days ago, after updating Mp3tag to version 3.00, when opening the application I came across a incompatibility warning and that it was necessary to update to 3.01. That's what I did, but then I realized that all the mapping settings I did were gone. I thought it happened because of the two consecutive updates, so I accepted.
Until, days later, I notice that my tag panel returned to an older version that I had edited before ... however, there was no plausible justification for this, since I had not updated or tampered with the files or anything. Again, I ignored and redid the tags.
Today, I went to edit the tags of a song by opening Mp3tag through the Windows context menu, and a warning appears saying "the file cannot be edited because it is corrupted" (which was not true). I went to open Mp3tag and: all the tags in the tag panel are gone. Without justification. I didn't touch the AppData folder or anything.
I would like to know if there is an explanation for these errors and I would like you to correct them. Thanks.
